Synopsis : In recent years, techniques of producing clean steel have progressed markedly. As a result, development of non-oriented silicon steel sheet with low core loss has been achieved in Kawasaki Steel Corporation, and the manufacture of RM7 (maximum core loss W15/50; 2.50 W/kg at thickness 0.50 mm) has become possible. RM7 is suitable to core materials for large rotating machines, such as generators, and for various static induction apparatus, and meets the needs of energy saving. Qualitative effects on core loss are also presented of such factors as size and texture of crystal grains and amount of nonmetallic inclusions. |
